1D Liner Felt

Easy to install, single diameter flexible liner for professional use.
Suitable for relining cast iron, clay, PVC, SDR, and concrete pipelines.

This unique material has a flexible laminate and stretches slightly into the pipe to allow the material to go through bends easily. The calculated length reduction is approx. -1% of the total liner length.

Our 1D Liners are suitable for relining waste and rainwater pipes inside and outside buildings, with the 4.5mm thickness recommended for outside of the building.

The liner is suitable for steam, hot water, ambient, or UV curing utilizing the correct resin compatible. Maximum temperature for steam or hot water curing +149 °F.

The liner must be protected against radial expansion with a calibration hose (inspection hatches, manholes, beginning and end, and other free spaces).
